Gaddafi's Exit

Why must a country's leader leave his country of birth and go into exile? This shows that the West can make and unmake you. They are now fed up with Gaddafi, so he must go. Why is it that they are not reporting the atrocities being committed by the Libyan rebells? This is a clear case of a carrot and stick situation. Now all the western powers are bent on ensuring that Gaddafi is kicked out. They are talking about he accepting an exit from Libya. Gaddafi as usual is very defiant and he has vowed not to leave Libya. I know the same thing will be done to whoever is installed as the new Libyan president. He will be manipulated by the west and they will get easy access to the oil and gas resources. Why is it that the  Yemeni president is not being presurised by the west to leave his country. They are careful in some countries where they support the leadership and will do everything not to jeopardise that cordial friendship. Peaceful protesters are being killed in the Yemeni capital and all that the western powers could do was to evacuate their embassy staff and non essential workforce. Why dont they impose a no- fly zone over Yemen, Bahrain and Syria. I keep on asking myself, is this the case of George Orwell's Animal Farm, where some animals are seen to be better than others? The moment Gaddafi leaves Libya, the west will do everything possible to fast track his extradition to the International Criminal Court in the Hague. The AU has also joined the bandwagon for Gaddafi's exit from Libya, his country of birth. Meanwhile he was seen as a major financier of the continental body, why are they now disowning him, is he not an African? The current African leaders should be wary of Greeks bearing gifts otherwise the same fate befalling Gaddafi currently will befall them in the near future.
